2 Claims.

This invention is concerned with the lubrication of the bearings by which an assembly of two metal plates'are operatively connected for rotation of one plate relative to the other.

An object of the invention is to provide an assemblyof metal plates, bearings by which one plate is supported by the other for rotation relative thereto, and bearing lubricating means requiring the minimum of attention.
